1, for Debian no package libegl1 2, for Debian libgles2 is virtual package 3, suggest to use Conflicts, Provides with Replaces

Hello zhangn1985,

1, for Debian no package libegl1

libegl1 is in Debian stretch

stretch-backports (libs): Vendor neutral GL dispatch library -- EGL support 
1.0.0+git20180308-2~bpo9+1: arm64

3, suggest to use Conflicts, Provides with Replaces Replaces: libegl1-mesa, libgles2, aml-mali-905 Provides: libegl1-mesa, libgles2, aml-mali-905 Conflicts: libegl1-mesa, libgles2, aml-mali-905

I will try this, thank you~

OK. When I update the Conflicts, Provides and Replaces GPU package failed to install.

dpkg: regarding .../linux-gpu-amlogic-s905x-arm-mali-m450-r7p0-fbdev_0.3_arm64.deb containing linux-gpu-amlogic-s905x-arm-mali-m450-r7p0-fbdev:
 libgles2-mesa:arm64 conflicts with libgles2
  linux-gpu-amlogic-s905x-arm-mali-m450-r7p0-fbdev provides libgles2 and is to be installed.

dpkg: error processing archive /root/linux-gpu-amlogic-s905x-arm-mali-m450-r7p0-fbdev_0.3_arm64.deb (--install):

zhangn1985 commented 6 years ago

I guess you already have libgles2-mesa installed, so can't install.

zhangn1985 commented 6 years ago

libegl1 is real package, and libegl1-mesa is dummy.

questions: linux-gpu-amlogic-s905x-arm-mali-m450-r7p0-fbdev_0.3_arm64.deb this package provides EGL, GLES2

when I check package: libgles2:arm64, I find it 

Conflicts: libgles2
Replaces: libgles2
Provides: libgles2

so if linux-gpu-amlogic-s905x-arm-mali-m450-r7p0-fbdev_0.3_arm64.deb provides egl and gles, I guess, you can follow this way.

this is my misunderstanding,close
